This article is for general information. Figures and examples are illustrative and can change; check the linked sources before making decisions.
Quick answer: the 50/30/20 rule splits your after-tax monthly income into three parts: 50% for needs, 30% for wants and 20% for savings and debt payments. It is a starting point, not a law. Depending on where you live and your fixed costs, you may need to adjust it.
What goes in each bucket
- Needs (50%): rent or mortgage, utilities, basic groceries, necessary transportation, insurance and minimum debt payments.
- Wants (30%): dining out, entertainment, subscriptions, travel, non-essential shopping.
- Savings and debt (20%): emergency fund, savings goals and extra debt payments.
The idea was popularized by Elizabeth Warren and Amelia Warren Tyagi in All Your Worth (2005).
Example with $3,000 take-home pay
| Bucket | Share | Amount |
|---|---|---|
| Needs | 50% | $1,500 |
| Wants | 30% | $900 |
| Savings and debt | 20% | $600 |
Calculate yours
How to apply it in 4 steps
- Write down your take-home pay, the amount that reaches your bank account.
- Review three months of spending on your statements.
- Sort each item into needs, wants or savings.
- Compare with 50/30/20 and adjust the biggest category first.
When it does not fit
If housing alone takes more than 50% of your income, you might try 60/20/20 or protect a smaller savings amount. If you have high-interest debt, putting more in the debt bucket can make sense. For ideas on trimming costs, see how to save on groceries and how to lower your electric bill.
Three income examples
The same rule applied to different monthly take-home pay (straight arithmetic):
| Take-home pay | Needs (50%) | Wants (30%) | Savings and debt (20%) |
|---|---|---|---|
| $2,000 | $1,000 | $600 | $400 |
| $3,000 | $1,500 | $900 | $600 |
| $4,500 | $2,250 | $1,350 | $900 |
What if your needs are above 50%?
This is common in expensive cities. Here is a made-up example with $3,000 take-home pay:
| Need | Amount |
|---|---|
| Rent | $1,300 |
| Utilities | $200 |
| Groceries | $400 |
| Transportation | $150 |
| Total | $2,050 (about 68% of income) |
That leaves about $950 (32%) for wants and savings. One approach is to protect a minimum for savings first and spend the rest on wants. A split you can keep is better than a perfect 50/30/20 you abandon.
FAQ
Is 50/30/20 based on gross or net income? Net, meaning after taxes.
Where should I keep the 20%? In a separate account so it is not mixed with daily spending. The CFPB has budgeting tools that can help.
Does it work with irregular income? You can use your average over several months and review every quarter.
